The key to whether you will be assigned is where the same strike puts are trading just before SPY goes ex. When someone exercises their calls for a dividend they are essentially selling the puts for the dividend amount, less cost of carry. If they can buy the put for less then the dividend and interest cost, it is a good exercise.

Cool I did not know that. I always just looked at the remainder of the value of the call premium - intrinsic value VS dividend amount.
